>Description:
MI's input does not use buffering.

At present the MI interface reads raw characters of from an unbuffered
FD.  This is to avoid several nasty buffer/race conditions.  That code
should be changed so that it registers its self with the event loop
(on the input FD) and then push commands up to MI as they arrive.

The serial code already does this.
